中文摘要本发明涉及一种基于多级稳压技术的电源故障诊断及保护装置。该装置由一级稳压电路、二级稳压电路、开关控制电路、欠压保护电路、过压保护电路和故障锁存电路组成。从功能上来说,该装置不仅具备两级的电源稳压功能,还能对电源运行中的过压和欠压故障进行诊断,当故障产生时能通过开关切断输出电压,同时故障锁存电路能够保持断电状态,直至重新上电。从结构上来说。该电路由6片封装较小的IC以及少量电阻电容组成,在具备稳压和保护功能的同时,电路体积做的很小,解决了通用电源保护电路电路复杂、体积庞大的问题,而且在设计中采用了集成的IC芯片,可靠性高,通用性强。

英文摘要The invention relates to a multistage voltage stabilization technology-based power source fault diagnosis and protection device. The device is composed of a first-stage voltage stabilizing circuit, a second-stage voltage stabilizing circuit, a switch control circuit, an under voltage protection circuit, an overvoltage protection circuit and a fault latch circuit. Functionally speaking, the device has a two-stage power source stabilizing function and can diagnose overvoltage and undervoltage faults in the operating process of a power source, and the device can cut off output voltage through a switch when a fault occurs, at the same time, the fault latch circuit can maintain a power-off state until re-electrification; structurally speaking, the circuit is composed of six small packaged ICs and a small number of resistors and capacitors, and therefore, the circuit has a voltage stabilizing function and a protection function, and the size of the circuit can be small, and thus, the problems of circuit complexity and large size of a general power source protection circuit can be solved; and the integrated IC chips are adopted in design, so that high reliability and high universality can be realized.
